Mandevilla plant named ‘Lanlouisiana’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Lanlouisiana’, characterized by its upright and vining plant habit; moderately vigorous to vigorous growth habit; relatively long internodes; large glossy dark green-colored leaves; freely flowering habit; and large scarlet red-colored flowers.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘LANLOUISIANA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Lanlouisiana’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Malause, France. The objective of the breeding program is to create new vining-type Mandevilla plants with numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France in June, 2009 of a proprietary selection of Mandevilla hybrida identified as code number 05-040-07, not patented, as the female, or seed parent with Mandevilla hybrida ‘Sunmandecrikin’, disclosed in U.S. Plant Pat. No. 17,736, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Malause, France in June, 2012.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since December, 2012 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lanlouisiana’. These characteristics in combination distinguish ‘Lanlouisiana’ as a new and distinct Mandevilla plant:

-   -   1. Upright and vining plant habit.     -   2. Moderately vigorous to vigorous growth habit.     -   3. Relatively long internodes.     -   4. Large glossy dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Large scarlet red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have longer internodes than         plants of the female parent selection.     -   2. Plants of the new Mandevilla and the female parent selection         differ in flower color as plants of the female parent selection         have pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent, ‘Sunmandecrikin’. Plants of the new Mandevilla differ primarily from plants of ‘Sunmandecrikin’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vigorous than plants of         ‘Sunmandecrikin’.     -   2. Plants of the new Mandevilla have longer internodes than         plants of ‘Sunmandecrikin’.     -   3. Plants of the new Mandevilla flower earlier than plants of         ‘Sunmandecrikin’.     -   4. Plants of the new Mandevilla and ‘Sunmandecrikin’ differ         slightly in flower color.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Lanarizona’, disclosed in U.S. Plant Pat. No. 23,672. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed primarily from plants of ‘Lanarizona’ in flower color as plants of ‘Lanarizona’ have white-colored flowers. In addition, plants of the new Mandevilla had smoother leaves than plants of ‘Lanarizona’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 21-cm containers in polyethylene-covered greenhouse in Malause, France and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 15° C. to 26° C. and night temperatures ranged from 14° C. to 15° C. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
